I am not an actual heat professional if that is what you're asking. I did oversee several HVAC mechanics at my previous job though so I do know a decent amount regarding heating and cooling systems. I was being sarcastic... My heating system is what I would call "ghetto rigged" right now in comparison to a standard system. I've decided to run heat tape down the back of each shelf and should have it done this week. Currently though I am using individual heat pads for each bin with thermostats in each bin and if needed I will adjust the placement of the heat mat to correct any temperature fluctuations. I also have a heat gun that I use to verify the temperature readings.
